摘要： A method of forming a bit line of a semiconductor memory device is performed as follows. A first interlayer insulating layer is formed over a semiconductor substrate in which an underlying structure is formed. A region of the first interlayer insulating layer is etched to form contact holes through which a contact region of the semiconductor substrate is exposed. A low-resistance tungsten layer is deposited on the entire surface including the contact holes, thus forming contacts. A CMP process is performed in order to mitigate surface roughness of the low-resistance tungsten layer. The low-resistance tungsten layer on the interlayer insulating layer is patterned in a bit line metal line pattern, forming a bit line.

摘要： A method of forming an isolation layer of a semiconductor device includes forming first trenches in an isolation region of a semiconductor substrate. Sidewalls and a bottom surface of each of the first trenches are oxidized by a radical oxidization process to form a first oxide layer. An oxidization-prevention spacer is formed on the sidewalls of each of the first trenches. Second trenches are formed in the isolation region below the corresponding first trenches, wherein each second trench is narrower and deeper than the corresponding first trench. The second trenches are filled with a second oxide layer. The first trenches are filled with an insulating layer.

摘要： The present invention relates to a method of manufacturing a flash memory device. The method includes the steps of forming cell gate patterns and select transistor gate patterns on a semiconductor substrate; forming a low dielectric layer on the resultant structure; etching the low dielectric layer, leavinin gaps adjacent the cell gate patterns; and, forming a nitride layer spacer on one side wall of each of the select transistor gate patterns. The resulting flash memory device has an improved rate of change in the threshold voltage and reduces the contact resistance when a self-aligned contact method is subsequently performed.
